image display with imtool

Hi Everyone.

Anyone can help me. If i have 20 slice image PET (256x256 dimensions, dicom format), how to me:

1)display all the slice?

2) at the same time, when i move the courser at every picture, i it will show the location(X, Y) and the pixel value(intensity) such as use imtool code.

Here is my try code: alldata = zeros(256, 256, 20); for K = 1 : 20 petname = sprintf('PET%03d.dcm', K); alldata(:, :, K) = combinedata; end

montage(alldata, []);

BUT IS DOES'T WORK

Anyone please help me

Sorry, this is my code

alldata = zeros(256, 256, 20);

for K = 1 : 20

petname = sprintf('PET%03d.dcm', K);

alldata(:, :, K) = dicomread(petname);

end

montage(alldata, []);

You need to show one image/slice at a time. For example you can use a slider callback to do it. Don't use montage(). Use imshow() and then call impixelinfo().

i Used imshow() and then call impixelinfo(). but it only one image. but i want adapt to all image.

Can you help me to give tutorial or any notes to build slider callback?

Sorry all, another question i have but i wrote at this space. please help me

Dear all,

this is my code to view CT image by slice

P = zeros(256, 256, 72);
for K = 1 : 72
    petname = sprintf('I4%03d.dcm', K);
    P(:,:,K) = dicomread(petname);
end
imshow3D(P)

then, this is my code for view SPECT image by slice,

Noted: all my 42 slice SPECT image stored in one file.

[spect map]=dicomread('128x128');
info = dicominfo('128x128');
gp=info.SliceThickness;
spect=(squeeze(spect));%smooth3
aa=size(spect);aa=aa(3);
imshow3D(spect);

Anybody can help me to fuse both SPECT and CT images for all slice?

You should ask the author of your imshow3D() function, not us I'm not aware of any such function, and there is no such function in MATLAB.

Maybe you can use volumeviewer() as a substitute if you cannot contact the author of imshow3d.
